Where at least thirty percent (30%) of the lots along a frontage on one side of a street in any block are occupied by buildings that deviate in setback more than five (5) feet from the required front yard, the minimum front yard for each lot along the frontage shall be established in the following manner:

1.   If all the buildings have a setback greater than five (5) feet more than the required front yard, the front yard shall be equivalent to the setback of the closest building to the street.

2.   If all the buildings are located more than five (5) feet closer to the street than the required front yard, the front yard shall be established five (5) feet closer to the street than the required front yard.

3.   If the provisions of subsection 1 or 2 do not apply, the front yard for each lot shall be determined as follows:

   A.   Interior and Double Frontage Lots (See Figure 8).  At the option of the lot owner, the front yard shall be established as the front yard required in the zone in which the lot is located or otherwise as follows:

      (1)   The front yard of a lot shall be established as an average of the setbacks of the principal buildings on the abutting lots to each side.

      (2)   Where a principal building is located on an abutting lot on one side only, the minimum front yard shall be equal to the setback of the principal building on the abutting lot.

   B.   Corner Lots (See Figure 8).  The minimum front yard of a corner lot shall be the front yard required for the zone in which it is located.

A conditional use may be granted by the Board of Adjustment modifying yard requirements when the owner or lawful occupant of property demonstrates that such person’s situation is peculiar to the property in question, that there is practical difficulty in complying with the dimensional requirements of this chapter, and the conditions of Section 165.52(5) can be met.
